STATS ATET BENJAMIN F. SILLIMAN, OF CLEVELAND, OHIO, ASSIGNOR TO THE CLEVELAND STEEL TOOL COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

STEAM-TRAIL.

To all whom it may concern:

Be it known that I, BENJAMIN F. SILLI- MAN, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Steam-Traps, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The type of apparatus to which the present invention relates, is designed in general for removing water of condensation from steam pipes, separators, heaters, engine cylinders and the like, without at the same time permitting the steam to be wasted.

The objectof the invention is the provision of a device of the type just referred to, that, while simple and economical in construction, will have the additional advantage of presenting its several operative parts in such condition as to permit their ready inspection and removal, should this become necessary in the course of operation.

To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing :-Figure 1 is a longitudinal vertical section of a trap embodying in preferred form my several improvements; Fig. 2 is partly an end elevation and partly a vertical transverse section of such trap; while Fig. 3 is partly a plan view and partly a horizontal section of an operative detail of the trap.

Referring to the several figures just described, the body of the trap will be seen to consist of a casing A of more or less familiar form provided with an inlet opening a that discharges directly into the interior of such casing, a deflecting plate a being provided, as usual, to direct. downwardly the water thus entering the trap. A drain opening a similarly opens directly into the interior of the casing. In the assembled condition of the trap, such casing is closed by a cover B in the form of a plate fitted to the opening Specification of Letters Patent.

passage Z) formed in the cover, is inclosed by a cap B that is in turn removably mounted upon such cover. Passage 6 is designed to register with another passage a, formed in the wall of easing A, that provides the exterior discharge opening of the trap. In the upper end of discharge pipe b, more over, thus seen to be inclosed by cap B, is

removably mounted a valve seat 6 wherewith a valve 0 reciprocably held in the pipe is designed to operate. Such valve is carried by a stem 0, the lower end of which extends downwardly below the lower end of the pipe, and is there secured in a manner now to be described, to a pivotal bucket 0, whereby operation of such valve is 'controlled.

Bucket C, while in general the same as the bucket-s heretofore employed in traps of the type in hand, is distinguished therefrom by having a pocket 0 formed in its bottom at the end adjacent to its pivotal axis, and the lower end of the valve stem 0' is secured bet-ween two ears 0 that rise in such pocket, by means of a pin 0 extending transversely through the lateral walls of the pocket and ears. Pivotal attachment of the bucket to the casing is secured by providing such bucket with two projecting lugs 0 adjacent to pocket 0 such lugs having tranversed alined apertures c in their outer ends, with which apertures similarly disposed pivots c on the lower ends of two resilient arms 0 are adapted to engage. These arms are preferable carried by an annular member C that is clamped or otherwise held between the cover B and the casing A of the trap, so as to be readily removed from the end of the discharge pipe, if desired. Should, instead, the valve require attention, the pipe I) may be bodily removed from the cover without without disturbing the external connections of the casing. It is thus rendered possible to install the trap permanently in place without providing separable connections be tween the supply and discharge lines and the trap. Obviously when the cover is ofii, the bucket as well as the ring whereby it is supported from the casing may both be removed.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a device of the character described, the combination of a discharge pipe, a valve controlling the flow of liquid therethrough, a pivotal bucket, and a pin passing through the lateral walls of said bucket and the end of the stem of said valve for connecting the latter with said bucket.

2. In a device of the character described, the combination of a discharge pipe, a valve controlling the flow of liquid therethrough, a pivotal bucket formed with a pocket at the end adjacent to its pivotal axis, and a pin passing through the lateral walls of such pocket and the lower end of the stem of said valve for connecting the latter with said bucket.

3. In a device of the character described, the combination of a discharge pipe, a valve controlling the flow of liquid therethrough, a pivotal bucket formed with a pocket at the end adjacent to its pivotal. axis, and with transversely alined ears in such pocket, the lower end of the stem of said valve lying between said ears, and a pin passing through the lateral walls of such pocket, such ears, and said stem, whereby said valve is connectedwith said bucket.

4t. In a device of the character described,

the combination of a casing, a cover therefor, a bucket within said casing for controlling the discharge of liquid therefrom, said bucket being provided with projecting lugs, and a member held between said casing and cover and provided with resilient depending arms adapted to detachably engage said lugs and thereby pivotally secure said bucket to said casing.

5. In a device of the character described, the combination of a casing, a cover therefor, a bucket within said casing for controlling the discharge of liquid therefrom, said bucket being provided with two projecting lugs having transversely alined apertures, and an annular member held between said casing and cover, and provided with resilient depending arms formed with transversely disposed pivots, such pivots being adapted to be sprung into engagement with the apertures in said lugs and thereby pivotally secure said bucket to said casing.

6. The body of the trap and a removable cover therefor, in combination with a bucket pivotally supported from said cover and provided with a depression in its bottom having parallel side walls, a valve rod extending into said depression and a coupling pin therefore projecting through said side walls, and a guide for the upper end of said valve rod to center the valve on its seat.

7 In steam traps, a bucket having a rela tively narrow and elongated depression in its bottom centrally at one end, in combination with a valve rod having its lower end extending into said depression, a pin transversely through the wall, said depression and said rod, and a fixed guide for the upper end of said rod in the exhaust passage for the trap.

Signed by me this 28th day of April, 1909.
